The resolution of the eye is ultimately limited by pupil diameter. What is the smallest diameter spot the eye can produce on the retina if the pupil diameter is 4.45 ? Assume light with a wavelength of = 600 . (Note: The distance from the pupil to the retina is 25.4 . In addition, the space between the pupil and the retina is filled with a fluid whose index of refraction is = 1.336.)
